Based on the knowledge sources provided, I can explain the difference between

issued_at

and

authenticated_at

in the

/whoami

response for Ory Kratos: 1. `authenticated_at`: This timestamp indicates when the user was authenticated, i.e., when they successfully logged in or when their identity was verified [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api). 2. `issued_at`: This timestamp represents when the session was issued. It's usually equal or close to the

authenticated_at

time [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api). The main difference is that

authenticated_at

specifically refers to the moment of authentication, while

issued_at

refers to when the session was created, which typically happens immediately after authentication. Here's an example from the knowledge sources showing both fields in a session response:

json {   "authenticated_at": "2020-09-03T21:32:47.5881038Z",   "issued_at": "2020-09-03T21:32:47.5642688Z" }

As you can see, these timestamps are very close to each other, with

issued_at

being slightly earlier in this case [Docs > Kratos > Self-service > Flows > Registration](https://www.ory.sh/docs/kratos/self-service/flows/user-registration#with-auto-login-on-registration).
